In its present embodiment the invention is applied to a coin-lock forcompartment doors which includes a back-plate fast upon the door at thekeeper for supporting the lock-casing, a coin-slot in the casing, shaftsextending through the easing and door for operating the lock, and acoinoperated mechanism on one of the shafts for controlling theoperation of the lock. Also included is a conventional till forcollecting and means for counting the coins, together with auxiliarylocks for protecting the till and permitting access to the compartmentwithout use of a coin. These features will be described only generallysince their nature and method of operation are well known in the art.

In the drawings, the machine comprises the generally rectangularback-plate 1 having at each corner a hole 2 for receiving a screw 3 tosecure the plate upon the outer surface of the door D. The oblong box orcasing 4 for the lock is adapted to be secured to the back-plate 1 byopposite screws 5 threaded into perforated lugs 6 at the bottom of thecasing, and a plate '7 slidably mounted on opposite lugs 9 at the top ofthe back-plate. From the inner surface of the casing 4, as seen in Figs.3 and 4, a lug 11 projects. EX- tending from the plate 7 is a stud 12which is held on the upper edge of a disk 13 fast on the forward end ofthe tubular shaft 14 whereby to hold the plate 7 in engagement with thelug 11. The opposite end of the tubular shaft 14 is squared at 15 toreceive a handle 16 to permit the disk 13 to be turned from the insideof the compartment. Pivoted on a screw 1'7 fast in the back-plate 1below the tubular shaft 14 is a stop-plate 18 which normally restsagainst a stud 19 on the back-plate to prevent the disk 13 from turningto permit the plate '7 to be lowered. At the edge of the back-plate 1spaced brackets or lugs 21 hold a spring 22, one end of which engages anear 23 of the disk 13 to normally urge it in a clockwise directionagainst the stop-plate 18. In the top of the lock-casing 4 is a smallaperture 24 for receiving an awl or similar implement, not shown. Byturning the handle 16 to turn the disk 13 against the pressure of thespring 22 from the stop-plate 18 the latter may be manually turned onthe screw 17 away from the stud 19. When the handle 16 is released thepressure of the spring 22 causes the disk 13 to be rotated beyond thestud 12. The awl may then be inserted in the aperture 24 and the plate'7 depressed to clear the lug 11. Upon removal of the lower screws 5,the casing 4 is then free to be withdrawn from the back-plate 1 in orderto permit access to the coin-operated mechanism therewithin.

The front of the casing 4 is recessed at 25, see Fig. 5, to permitaccess to the stop-plate 18 and the till without detaching the casingfrom the back-plate 1. The recess 25 is normally closed by a closelyfitting rectangular plate or cash-door 26 which is adapted to be madefast therein by means of the lock 2'7 engaging a lug 28 on the inside ofthe casing.

In horizontal alinement with the keeper 29 and a stop-lug 30 fast on theside of the casing 4, a bolt 31 is supported for horizontal movement bya bracket 32 fast on the back-plate 1. At the inner side thereof thebolt 31 is slotted at 33 to receive the bracket 32 and at its outer endis slidably mounted between the opposite lugs 34 fast on theback-plate 1. The upper end of the spring 22 urges the bolt 31 towardthe keeper 29, a shoulder 35 on the bolt engaging the lower lug 34 toretain the bolt within the casing 4. Depending from the bolt 31 belowthe slot 33 is a leg 36 engageable by the disk 13 when the inner handle16 is turned to withdraw the bolt from the keeper toward the stop 30 toopen the door.

Above the bolt 31 a cylinder-lock 37 is let into the casing 4. Upon therear end of the bolt 31 is a lateral lug 38 which is adapted to .beengaged by an arm 39 mounted on the lock 3'7. The lock 3'? maintains thearm 39 normally in the inoperative position seen in full lines in Fig.11, subject to be turned by means of the attendants passkey to theposition shown by broken lines. In the latter condition the lug 38 isengaged to draw the bolt 31 from the keeper 29 against the spring 22.

The coin-operated mechanism is carried on a horizontal spindle or shaft40 journaled in bearings 41 in the front of the casing 4. The shaft 46projects into the tubular shaft 14, being adapted to be freely rotatabletherein as seen in Fig. 3. The shaft 46 is adapted to be manuallyrotated from a bar or handle 42 secured to its forward end, the handlebeing rotatable without the casing 4 to provide for convenientmanipulation. Fast on the shaft 40 is a ratchet-plate 43 connected byscrews 46 to an opposite rearward plate 48. The screws 46 pass throughshouldered members 49 which space the plates 43 and 48 in parallelrelation. Fixed between the plates 43 and 43 is an inclined coin-rest 51provided with a longitudinal slot 52, the parts last describedconstituting in their assembled relation a coin-carrier, hereinafterdesignated in general by the reference character 55.

It will be observed that the coin-carrier 55 is rockable about the axison the shaft 40 by means of the handle 42. A wire spring 56 coiledaround the shaft 40 has one end 57 fastened to the coinrest 51, and itsopposite end 53 is held under tensicn against the side of a stud .59which projects on the inside of the casing front. The spring 56 tends tomaintain the coin-carrier 55 in the position of rest illustrated in 4with the ratchetplate 43 swung back beyond the coin-slot or way 62 shownin Figs. 1 and 2. With the coin-carrier 55 in this position thecoin-rest 51 is alined with the coin-slot 62 whereby to adapt it toreceive the coin inserted therethrough and the spring 56 acts to returnthe coin-carrier to this position after each swinging movement thereofby the shaft 40.

A pawl 63 pivoted at 64 to the front of the casing 4 is urged by aspring 65 upon the teeth 66 on the rearward edge of the ratchet-plate 43to prevent the return of the coin-carrier 55 unless or until the coin isdischarged from the carrier, this part of the mechanism beingspecifically described in my patent referred to last above. Suf fice itto herein state that the pawl 63 engages with the teeth 66 on theratchet-plate 43 when the coin-carrier 55 is operating with a coin inplace thereon to prevent retrogressive movement of the carrier. The pawl63 does not cooperate with the ratchet unless a coin is in place on thecarrier, being held from engagement with the teeth thereof by an element65 termed the presser-plate which forms the energizing means forunlocking the mechanism. The presser-plate 67 has a cam-shaped edge 68which normally holds the toe of the pawl 63 away from the ratchet 43, asseen in 4, by means of a spring 69 on the stud 64, the spring 69 beingconnected to a tie-rod '70 pivotally mounted on the plate 67.

The presser-lever 67 has its hub 71 mounted free to turn on thecross-shaft 40 and is formed with a lateral stud '72. A connecter-plate73 is slotted at 74 for sliding movement transversely on the shaft 40.At its upper extremity the connector-plate 73 is forked at 75 to receivethe lower bushing 49 whereby the plate '73 is connected to be carriedacross the shaft 40 by movement of the coin-carrier 55. The plate 73 isrecessed at 76 to receive the stud 72 and is provided with a finger orcoin-presser '7'? which projects through the v55 is in position toreceive the coin as indicated by dotted lines in Fig. 4. The end of thecoinpresser 7'7 is adapted to engage the coin in the carrier 55 to causethe presser-lever 67 to be moved with the carrier by the connecter-plate'73 to unlock the doorfrom the outside.

In order that the coin may act positively against the finger 7'7 it isheld against the coinrest 51 by means engaging its edges. As shown inFig. 5 the ratchet-plate 43 is formed with an car '78 bent to overhangthe edge of the coin as the latter slides down to position upon therest. At the opposite side of the coin-rest 51 is a coi11- holdercomprising a lever '79 pivoted on a stud 80 fast on the rear plate 48.The coin-holder '79 has an offset portion 81 adapted to overlie the edgeof the coin whereby it cooperates with the car '78 to hold the coinagainst the rest 51. The coin-holder '79 is normally held in position toengage with the coin by a spring-pressed detcnt latch 82 pivoted betweenthe sides of the coincarrier 55. The detent-latch 82 has a lateral arm83 which is normally engaged on the edge of the coin-holder '79 to spacethe lower end of the latch from the coin-rest and permit the coin toslide therebetween to position upon the car '78 and offset portion 8.The latch 82 has a depending dog 84 which engages the coin-holder '79 tomain tain the latter in coin-retaining position until the throw of thecoin-carrier 05 has been almost completed, whereupon a tailpiece orstriker 85 of the latch engages the side of the casing 4, see '7, torock the dog oil the coin-holder and permit it to swing upwardly torelease the coin.

A contact-member or arm 86 formed on the presser-lever 67 extendsupwardly to engage depend ng pivoted fingers 8'7 an 33 of the counter89. When the presser-lev r 67 is turn d with the coin-carrier 55 tounlock the door, the arm 86 lifts the finger 8'7, see Fig. 6, to changethe reading 'of the counter to record the coin in the carrier. afterdischarge of the coin and the retraction of the lever 6'7 upon the pawl63 the arm 86 engages the finger 88, causing it to pivot to the positionseen in Fig. "I and thereby reset the counter 89 for the next coin. M

Fast on the presser-leverd? is referably a projecting bracket 91 havinga bent-over portion or lifter 92 which extends along the rear surface ofthe plate 18. If desired, the lifter 92 may be integral with or attacheddirectly upon the presser-lever 6'7. Adapted to radially alined with thebent-over portion 92 in respect to the axis 40 is a lug or driver 93which projects rearwardly from the plate 18. When a coin has beendeposited and the handle 42 turned the bent-over portion 92 and the lug93 move together in concentric paths to draw the bolt 31 against thespring 22 by connecting means described hereinafter.

A feature of the present invention comprises connecting means on thebolt 31 for unlocking the door with the front handle 12 only when a coinhas been deposited in the slot 62, which is adapted to preventretrogression of the coincarrier until the coin has been discharged andto insure the immediate full return of the carrier to coin-receivingposition whereby the lock always in condition to collect revenue savewhile the front handle is being operated. Fur thermore, the connectingmeans permits the handle a2 and bolt 31 to be operated any num-- ber oftimes after the coin has been discharged until the bolt is subsequentlyoperated independently of the handle 42, such as when the door closesupon the keeper, or the inner handle turned. In the instant embodimentof the invention, said connecting means includes a coun tersunk screw 94fast in the leg 36 of the bolt and projecting from the forward surfacethere of to receive a flanged nut 96 screwed ti -dy thereon, see Figs.12 and 13. Pivoted on the core 9'7 of the nut 96- is a lever 98 having ahub 99 and arms 101 and 102 extending radially therefrom. The arms 101and 102 are spaced by the hub 99 forwardly from the leg 36 to provideroom therebetween for an arcuate bar or link 10%. One end of the link2104 is pivotally connected with the extremity of the arm 101, thelatter being bored to receive a stud 10'? fast on said link end.

At the free end, the link 104 is formed with upper and lower lips 108and 109 which are adapted to be engaged by the lifter and driver members92 and 93, respectively, in a manner to be later described, to open thelook. at the ivot end the link 10 1 is provided laterally with upper andlower flanges 111 and 112, respective ly. One end of a spring 113 coiledaround the core 9'7 is seated in a notched foot 114 on the leg 36. Theother end of the spring 113 is retained by an ear 116 to bear againstthe lower flange 112 to urge the lever 98 to rotate on the core 9'7 in aclockwise direction.

Referring to Fig. 8, the lever 98 is normally held by the spring 113 tomaintain the link 10 1 substantially in the horizontal with the loweredge thereof resting upon the convolutions or the spring 113 on the core97 and the upper flange 111 pressed against the lower edge of the bolt31. The pressure of the spring 113 velops sufficient f iction betweenthe flange and the bolt 31, and the flange 112 and spring 113,respectively, to retain the lir against gravity in any position it maybe tu to on the stud 107. 10 i is curved at 117.

When the door is locked the link 104 is below the plane of the bracket32, consequently when the bolt 31 is drawn against the spring 22 linkdoes not touch the bracket. However, i the link 104 has been raised andthe bolt drawn, the lower end of the bracket 32 or on the curved edge117 and pushes the linl; down to normal horizontal position, see Fig.11, if the link is unsupported save by the pressure of the spring 113.When the link is supported in raised position by means in addition tospring 113 such, for instance, as by the lifter de- 111 the we .ied Theupper edge of the link 92, and the bolt 31 is pushed by the driver lugmovement of the curved edge 117 upon the bracket 32 will force the lever98 to pivot on the core 9'7 against the spring 113, as seen in Fig. 10.Upon withdrawal of the lifter 92 and driver-lug 93 the bolt 31 isexpelled by the spring 22 and the lever 98 is returned to normalposition by the spring 113. Due to the friction on the upper and lowerflanges 111 and 112 however, the return of the link 10 1 is onlypartially effected, it proceeding only until the curved edge 117 leavesthe bracket 32; and the link 10 1' is left suspended with its upper andlower lips 1G8 and 109 straddling the arcuate path of the.

driver-lug 93.

The construction and arrangement of the device having now been describedin detail, the method of operation of the connecting means inconjunction with the coin-operated mechanism will next be explained.

Coin-locks of the type herein considered are 1:

lilo;

usually applied to doors having spring hinges or other suitable meansfor constantly urging the door to closed position to cause the bolt tobe slid inwardly upon the bracket 32 when passing over the keeper 29before locking therein. The elements of the connecting means on the bolt31 are therefore normally at rest, with the link 104 resting in thehorizontal on the nut 96 and the lever 98 held by the spring 113 againstthe lower edge of the bolt 31, as shown most clearly in Fig. 8. Thecoin-operated mechanism is also at rest as shown in Fig. 4, thecoin-rest 51 alined with the coin-slot 62 to receive a cointherethrough, the presser-plate 6'7 being held upon the pawl 63, and theconnecter-plate '73 held by the shouldered spacer 49 to engage the stud72 in the recess '76.

When a coin C is deposited in the coin-slot 62 to open the door, itimmediately slides to rest between the ear '78 and offset portion 81,becoming thereby a means for locking the connecterplate '73 inengagement with the coin-carrier 55. The front handle 42 is then turnedfrom the position shown in Fig. 1, swinging the coin-carrier on theshaft 40 in a. contra-clockwise direction from the position shown inFig. 4 and causing the connecter-plate '73 to shoulder upwardly upon thestud '72, thus rotating the presser-plate 67 about its axis 40. The camsurface 68 is lifted from the pawl 63 to permit the latter to engage theteeth 66 on the cam-plate for preventing retrogresison of thecoin-operated mechanism should the handle 42 be released.

As the swinging movement progresses the lifter 92 moves under the lowerlip 109 to lift the link 104 to the position shown in Fig. 9 wherein itprojects into the arcuate path of the pusher-lug 93. While thepusher-lug 93 advances to engage under the lip 108 and begins to pressthe link 104 to slide the bolt 31 inwardly from the keeper, thecoin-operated mechanism is carried toward the completion of its throw.The striker engages on the side of the casing 4 to tilt the detent-latch82, thereby removing the dog 84 and permitting the coin-holder '79 toswing diagonally outwardly to remove its offset portion 81 and free thecoin. The tension of the spring 69 causes the presserplate 6'7 to urgethe stud 72 upon the connecterplate '73 and cause the connecter-plate toswing across the shaft 40, as shown in Fig. 7, and discharge the coin.This movement releases the stud '72, causing the presser-plate 67 to bepivoted quickly to its original position on the pawl 63 under tension ofthe spring 69. The lifter 92 is thereby returned and the bolt 31 iscompletely withdrawn from the keeper through the continued rotation ofthe handle 42, the pusher 93 being engaged under the lip 108. Toward theend of the withdrawing movement the curved edge 11'? of the link 104engages the bracket 32 which tends to swing the link 104 toward thehorizontal about the stud 107. This efiect is prevented by the pusher 93which sustains the free end of the link 104 causing the bracket 32 toforce the pivoted end of the link downwardly against the spring 113, andtilting the lever 98 in a contraclockwise direction.

Referring to Fig. 10, wherein the culmination of this unlockingoperation is illustrated, the bolt 31 engages the stop 30 which limitsthe movement of the pusher 93 and handle 42 when the bolt has beencompletely withdrawn from the keeper. The handle 42 may then be releasedcausing the coin-operated mechanism to return in a clockwise directionto the position of rest with the coinrest 51 alined to receive a cointhrough the slot 62. The pusher 93 being thus removed from the link 104the spring 22 becomes operative to slide the bolt 31 outwardly to itsnormal position on the lug 34. Sliding of the bolt outwardly moves theconnecting means from the bracket 32 and the spring 113 swings the lever98 in a clockwise direction, lifting the pivoted end of the link 104until the upper flange 111 engages the lower edge of the bolt 31.Although the pusher 93 has been withdrawn from the lip 108 the link 104remains elevated above the nut 96 and in the arcuate path of the pusherdue to the friction between the flange 111 and the bolt edge, and theflange 112 and the spring 113, respectively.

The patron, having once turned the handle 42 to discharge the coin andwithdraw the bolt 31 from the keeper 29, customarily opens the door toenter the compartment before releasing the handle. The handle 42 is thenreleased and the door closes upon the patron, causing the bolt to bepressed backwardly by the edge of the keeper 29 as indicated in Fig. 2,the keeper thereby acting to slide the bolt independently of the fronthandle 42. This movement being accomplished without useof the pusher 93,the camming action 100 of the bracket 32 on the curved edge 11'? causesthe link 104 to pivot at the stud 107 to lie in inoperative positionupon the core 97. This is illustrated in Fig. 11, wherein it will beobserved that the lip 108 is depressed below the arcuate path of thepusher 93, rendering it impossible thereafter to operatively engage thecoin-operated mechanism with the connecting means on the bolt 31 withoutuse of the lifter 92. In other words, sliding of the bolt inwardly byits contact with 110 the edge of the keeper 29 disconnects it fromcontrol by the handle 42. When the bolt has passed within the keeper itis returned upon the lug 34 by the spring 22, causing the connectingmeans to be carried away from the bracket 32 in the condition of restshown in Fig. 8.

Frequently it is found that the patron seeking entrance neglects to openthe door of the compartment before releasing the handle 42 to return thebolt 31 to latch within the keeper 29. The link 104 is then held inelevated position to operatively receive the pusher 93 without requiringuse of the lifter 92. Therefore, in order to thereafter enter thecompartment it is but necessary that the patron repeat the openingoperation of turning the handle 42, without depositing another coin.This causes the coin-carrier 55 to swing to bring the pusher 93 underthe lip 108 and carry the bolt 31 and connecting means thereonbackwardly in the same manner as described above, the pusher supportingthe link 104 against the bracket 32 and the spring 113 and thecooperating frictional surfaces coacting to return the link in raisedposition. Upon subsequent closing of the door, the keeper 29 slides thebolt to lower the connecting link 104 below the path of the pusher 93.

When the patron leaves the compartment the bolt 31 is withdrawn byactuation of the camplate 13 by the inner handle 16, and when the handleis released the bolt is returned upon the stud 34 by means of the spring22. The door then closes upon the keeper 29, the bolt being slid to passwithin the keeper and returned to latch therein. The compartment doorcoinlock is thus again established as shown in Fig. 4 to repeat thecycle of use as described above.

It will be observed that mounting the connecting means on the bolt 31simplifies the construction and assembly of the parts of the mechanism,

affording a more efiicient operation and distribution thereof with thelock-casing.

The invention provides a particularly simple device on the lock-bolt forconnecting the belt for control by the front handle when a coin has beendeposited until the bolt is actuated independently by the keeper 29 orby the inner handle 16. The device thus guards against obliging thepatron to deposit a second coin to draw the bolt upon his failure toopen the door after first drawing the bolt. By means of the mechanismdescribed the connecting means is positively lowered to inoperativeposition upon operation of the bolt by means independent of the fronthandle, rendering it impossible to thereafter withdraw the bolt by meansof the front handle until an additional coin is deposited.

After the connecting means is moved to operative position and the boltis drawn the coin-carrier is automatically returned to alinement withthe coin-slot in the casing, thereby restoring the lock to condition tocollect revenue without the services of an attendant or the necessity offurther manipulation by the patron. Being thus in the condition toreceive the coin at all times, save when the front handle is beingturned, the lock is especially useful for doors of compartments intendedto accommodate a plurality of patrons entering at different times.

Moreover, the device is practically proof against improper manipulationwithout use of a coin and. the construction of the casing is such thatthe machine cannot be tampered with and its contents stolen.

While I have herein described and illustrated the device as embodied ina preferred form of construction it is to be understood that theconstruction and arrangement of the parts of the mechanism may be variedas desired without departing from the spirit and scope of the invention.Therefore, without limiting myself in this respect, I claim:
